# Wave Character of the Time Dependent Ginzburg Landau Equation and the Fluctuating Pair Propagator in Superconductors*)

Progress of Theoretical Physics, Oct 1971

The time dependent Ginzburg Landau equation and the fluctuation propagator of a superconductor in a static electromagnetic field are examined to the next order of the small parameters 1/εFτ and T/εF, where εF is the Fermi energy and τ the relaxation time. The coefficient of the time derivative of the order parameter becomes a complex number, whose imaginary part is of order of T/εF smaller than the real part. This term is shown to be important for Hall effect due to the fluctuation near Tc, which has not been expected in the usual approximation. The argeement cover the cases of arbitrary mean free paths near Tc and of arbitrary temperatures except T≪Tc.
